Aaron - well said! I have been very frustrated trying to work this out with the GDC.

Just a clarification on the switches you mentioned. There is a similar part to the E79-20A. It's the Honeywell 2DM301.

The Omron part you mentioned is usually referred to as a "cheat" switch - on with door closed, off with door open, with optional override by pulling out the plunger during maintenance. Which could be still used for a steady ON or steady OFF, but one needs to be more careful about not reaching the momentary "plunger fully in" state.
